Gracemont (microarchitecture)
Gracemont is a microarchitecture for low-power processors used in systems on a chip (SoCs) made by Intel, and is the successor to Tremont. Like its predecessor, it is also implemented as low-power cores in a hybrid design of the Alder Lake processors.[2]

Design
Gracemont is the 4th generation out-of-order low-power Atom microarchitecture, built on the Intel 7 manufacturing process.
The Gracemont microarchitecture has the following enhancements over Tremont:[3][4]
Technology
- Intel 7 manufacturing process
- SoC (System on a chip) architecture
- 3D tri-gate transistors
- 64 KB L1 instruction cache, up from 32 KB in Tremont[4]
- 2 MB shared L2 cache per 4-core module[4]
- Intel Xe (Gen12.2) GPU with DirectX 12, OpenGL 4.6, Vulkan 1.2, OpenGL ES 3.2 and OpenCL 3.0 support.
- 10 W thermal design power (TDP) desktop processors
- 6 W TDP mobile processors
